Cocking Lime Works Factory : Sussex

The Cocking Lime Works Factory was last used by the Dudman Group of Companies in 1999, when all work ceased at both of their Cocking sites, Since then this abandoned Cocking Lime Works factory has just been left to rot and mature into a very beautiful, derelict and photogenic site that it is now.

Is this place easily accessible? I was thinking of wandering up here with a friend to do some photography, but i don’t know if there are any restrictions.
(I was planning on doing some night photography).
